H3K36 methylation regulates cell plasticity and regeneration in the intestinal epithelium.

Plasticity is needed during development and homeostasis to generate diverse cell types from stem and progenitor cells. Following differentiation, plasticity must be restricted in specialized cells to maintain tissue integrity and function. For this reason, specialized cell identity is stable under homeostatic conditions; however, cells in some tissues regain plasticity during injury-induced regeneration.

Comparing and assessing physical activity and sedentary behaviour guidelines for different populations with and without chronic conditions and/or disabilities: a systematic review protocol.

Physical activity guidelines targeting different populations with and without chronic diseases or disabilities are required to meet the diverse functional and physiological needs experienced by different subgroups of people to achieve optimal health benefits. As the importance of physical activity guidelines in promoting optimal health and well-being becomes increasingly recognised, there is a critical need for their systematic evaluation to ensure they remain effective, applicable and aligned with evolving health needs and scientific insights. This study aims to systematically review, critically evaluate, and compare global physical activity and sedentary behaviour guidelines on frequency, intensity, time, and type of exercise for adults, pregnant and postpartum women, and people living with chronic conditions and/or disabilities.

Light Walking Patterns and Postprandial Cardiometabolic Responses in Young Obese Adults: A Randomized Crossover Study.

Context: Recent studies suggest that light-intensity physical activity may enhance cardiometabolic health and reduce mortality risk in adults. However, more information is required to understand the patterns of light-intensity physical activity and postprandial cardiometabolic health.

Objective: This study examined the effects of different light-intensity walking patterns on postprandial cardiometabolic responses in young obese adults.

Effect of Interrupting Prolonged Sitting with Frequent Activity Breaks on Postprandial Glycemia and Insulin Sensitivity in Adults with Type 1 Diabetes on Continuous Subcutaneous Insulin Infusion Therapy: A Randomized Crossover Pilot Trial.

This study examined acute effects of interrupting prolonged sitting with short activity breaks on postprandial glucose/insulin responses and estimations of insulin sensitivity in adults with type 1 diabetes (T1D). In a randomized crossover trial, eight adults (age = 46 ± 14 years [mean ± SD], body mass index [BMI] = 27.2 ± 3.
